As for the true coil in the rear. I dont see the real advantage (in my opinion which isnt very valid most times) for all the extra work you have to do. Now if you do a custom rear suspension with new arms and stuff then ya go for it.sigpic"If one does not fail at times, then one has not challenged himself." -Ferdinand Porsche

Rear coil overs were used on the old M3 race cars to easily replace damaged parts or quickly change spring rates during a race.
People like us do rear coil overs because we think its cool. There is NOT a huge advantage to doing it and the added expense is pretty significant. The loss of wheel well space is a problem too.

Side note, I was doing some research and for out that if you wanted externally adjustable rear Koni shocks you can use some from a 1977 Porsche 911. Apparently it is what TKline sells, they just rebrand the part number. If you go through KoniMarket its about $380 somthing a pair with free shipping.sigpic

Usually a 4 to 5 inch spring plus helper springs on an inverted shock will allow enough clearance for most 17" wheels on E30s.
And yes I tested a standard eye-to-eye shock (like a QA1 or AFCO) with the spring in the stock location. You just need a double shear bracket to mount it to the stock location (or since you are making your own strut bar you could make your own bracket as well)Last edited by acolella76; 03-02-2013, 03:01 PM.-Alex
